Headless screw fixation of unstable ulnar styloid base fractures after distal radial fractures fixation.

Ulnar styloid fractures occur frequently concomitant with distal radial fractures. Although unstable distal radial fractures are mostly surgically treated, ulnar styloid fractures are often ignored. Unstable fractures at the base of the ulnar styloid may lead to persistent ulnar pain, due to distal radioulnar joint instability or ulnar styloid non-union.

Analysis of trapeziometacarpal prosthesis cup position with respect to the trapezial anatomy.

The purpose of this study was to analyse the anatomy of the trapezium with regard to cup position in trapeziometacarpal replacement and identify those trapeziums that are at risk of cup perforation through the trapezoid articular surface. The width of the proximal and distal articular surface and the height of the trapezium and second metacarpal facet were measured on 96 peritrapezial views reconstructed from computed tomography scans. The trapezoid articular surface of the trapezium (TRAST) angle was calculated, and four different cup designs were virtually positioned centrally in the trapezium and parallel to the proximal articular surface.

Arthroscopic Volar Extrinsic Plicature of the Volar Extrinsic Ligaments for Chronic Volar Scapholunate Instability.

The scapholunate ligamentous complex consists of the scapholunate interosseous ligament and the surrounding extrinsic ligamentous system. In cases of chronic scapholunate instability, stabilizing the extrinsic ligaments is crucial. This article presents an arthroscopic capsuloligamentous reinforcement plicature that focuses on tightening the volar scapholunate extrinsic ligaments, namely the radioscaphocapitate ligament and long radiolunate ligament, along with indirect tightening of the volar scapholunate interosseous ligament.

Arthroscopical Reinforcement of an Isolated Insufficiency of the Radioscaphocapitate Ligament to Treat Dynamic Radioscaphoid Instability: A Case Report.

The radioscaphocapitate ligament is part of the stabilizatory complex of the scaphoid. Isolated injury resulting in persistent radioscaphoid instability is rarely reported. The authors propose a technique for arthroscopic reinforcement.

A Stepwise Intraoperative Protocol to Minimize Complications after Volar Plating.

 Although outcome of volar plating is generally good, care should be taken to avoid specific iatrogenic and preventable complications, with an incidence reporting averaging 15%. Flexor tendon rupture due to a prominent plate, extensor tendon rupture due to a dorsal protruding screw tips, cartilage lesions due to intra-articular screw placement, loss of reduction due to insufficient stability, and persisting ulnar pain with distal radioulnar joint instability due to unstable triangular fibrocartilaginous complex lesions or unstable ulnar styloid base fractures all have been described.  We believe that a majority of these complications can be prevented by meticulous assessment of several intraoperative parameters during volar plating.

Standardised Tendon Fenestration with ITEC-Technique for Lateral Epicondylosis with Injection of Betamethasone versus Autologous Blood.

Infiltration is one of the treatment options for lateral epicondylosis, a degenerative process in the tendon of the musculus extensor carpi radialis brevis. The aim of this study was to evaluate the clinical outcome of a standardised fenestration technique, the Instant Tennis Elbow Cure (ITEC) technique, with injection of betamethasone versus autologous blood. A prospective comparative study was performed.

Radiological imaging of the trapeziometacarpal joint: a historical and clinical perspective.

The opposable thumb provides both stability and mobility and is needed to accomplish different prehensile tasks. The trapezium is a complex bone, with a distal articular surface that is convex in the sagittal plane of the thumb and concave in the coronal plane of the thumb. The numerous additional articulations with the carpus and the oblique orientation to the main plane of the hand makes it difficult to evaluate the trapeziometacarpal joint using standard hand or wrist radiographic views.

Minimally Invasive Pronator Quadratus Sparing Approach versus Extended Flexor Carpi Radialis Approach with Pronator Quadratus Repair for Volar Plating in Distal Radial Fractures.

 Several volar plating techniques exist to treat distal radial fractures.  We investigated minimally invasive plate osteosynthesis (MIPO) with pronator quadratus (PQ) sparing versus conventional flexor carpi radialis approach for volar plating with PQ repair after distal radial fractures during the first postoperative year.  Prospective data of two consecutive cohorts were compared: 62 patients in MIPO group with an average age of 61.

Addition-Subtraction Osteotomy With Ligamentoplasty for Symptomatic Trapezial Dysplasia With Metacarpal Instability: A 10-Year Follow-Up.

Purpose: Symptomatic trapezial dysplasia with metacarpal instability in a nonarthritic joint can lead to a disabling condition characterized by decreased pain, mobility, and strength. Bony correction may be required in dysplastic joints, because soft tissue correction might be insufficient to stabilize the trapeziometacarpal (TMC) joint. We combined 2 techniques described previously, an abduction-extension osteotomy of the first metacarpal and an opening wedge osteotomy of the trapezium, including a ligament reconstruction (hemi-flexor carpi radialis).

Perspectives and Consensus among International Orthopaedic Surgeons during Initial and Mid-lockdown Phases of Coronavirus Disease.

With a lot of uncertainty, unclear, and frequently changing management protocols, COVID-19 has significantly impacted the orthopaedic surgical practice during this pandemic crisis. Surgeons around the world needed closed introspection, contemplation, and prospective consensual recommendations for safe surgical practice and prevention of viral contamination. One hundred orthopaedic surgeons from 50 countries were sent a Google online form with a questionnaire explicating protocols for admission, surgeries, discharge, follow-up, relevant information affecting their surgical practices, difficulties faced, and many more important issues that happened during and after the lockdown.

Standardized Tendon Fenestration with Injection of Autologous Blood for Treatment of Lateral Epicondylitis.

Lateral epicondylitis (LE) of the elbow is often treated with conservative methods. Several techniques including injections with different substances are widely performed. No standardization exists.

Clinical and ultrasonographical follow-up after standard removal of distal radius volar plates positioned distal to the watershed line.

Marginal fracture types of the distal radius may require volar plate positioning distal to the watershed line. Subsequently, plate prominence with direct friction with the flexor tendons occurs which is associated with flexor tendon pathology. Standard plate removal can be proposed.

Short-Term Results after Total Trapeziectomy with a Poly-L/D-Lactide Spacer.

 Proximal migration of the first metacarpal can be seen after total trapeziectomy and various techniques have been described to prevent this subsidence.  We hypothesized the insertion of a poly-L/D-lactide spacer to prevent proximal migration of the first metacarpal without the need of an additional ligament reconstruction, allowing early mobilization and less demanding rehabilitation.  Ten thumbs were treated with a total trapeziectomy and insertion of a poly-L/D-lactide scaffold.

Ivory arthroplasty for trapeziometacarpal osteoarthritis: 10-year follow-up.

This prospective study investigates long-term functional outcome after total trapeziometacarpal joint replacement with the Ivory arthroplasty for trapeziometacarpal joint osteoarthritis. Clinical outcome, overall function, pain, and radiologic outcome after a minimum of 10 years were evaluated for 26 Ivory arthroplasty in 24 patients. Two patients had bilateral arthroplasties.

Midterm Follow-up of Treating Volar Marginal Rim Fractures with Variable Angle Lcp Volar Rim Distal Radius Plates.

Background: Specific treatment of the volar marginal rim fragment of distal radius fractures avoids occurance of volar radiocarpal dislocation. Although several fixation systems are available to capture this fragment, adequately maintaining internal fixation is difficult. We present our experience of the first 10 cases using the 2.

De Quervain Tenosynovitis Following Trapeziometacarpal Ball-and-Socket Joint Replacement.

Background One of the surgical treatment options for trapeziometacarpal (TMC) joint arthritis is a prosthetic ball-and-socket replacement. One of the complications in the postoperative setting is de Quervain tendinopathy. Purposes Although this complication has been reported following a resection athroplasty, we questioned whether lengthening of the thumb following the Ivory (Memometal, Stryker Corporate, Kalamazoo, MI, USA) ball-and-socket arthroplasty could be a causal factor.

Addition-subtraction osteotomy without ligamentoplasty for symptomatic trapezial dysplasia with metacarpal instability.

Trapeziometacarpal joint pain is often associated with a dynamic adduction deformity of the thumb metacarpal, combined with radial subluxation at the base of the thumb metacarpal, due to trapeziometacarpal dysplasia. Addition-subtraction osteotomy is a surgical option to correct the bony deformity when conservative treatment fails. Eight patients who underwent surgery with this technique were prospectively evaluated.

Primary shortening of the forearm and Sauvé-Kapandji for severely comminuted fractures of the distal forearm in elderly patients: a case report.

We report a case of an elderly female who sustained a severely comminuted distal radial and ulnar fracture, treated by shortening of the forearm, combined with a primary Sauvé-Kapandji procedure and volar plating of the distal radius.

Treatment of fractures of the proximal phalanx of long fingers with an isometric traction splint.

Treatment of fractures of the proximal phalanx of the long fingers remains difficult and challenging ; several options have been used. We report our experience with an isometric traction splint, modified from the Southampton design. A cohort of 32 patients with displaced fractures of a proximal phalanx was treated and assessed retrospectively after a short term (9 weeks after splint application).

Reconstruction of the medial patellofemoral ligament for patellar instability using an autologous gracilis tendon graft.

Patellofemoral dislocations are common. In cases with recurrence or residual instability, surgical intervention is usually considered. Numerous treatment protocols have been used in the past to treat patellofemoral instability secondary to patella dislocation.
